I'm assuming you are asking for the flow rate of the stock Fuel Pump when you refer to "size."

Well, Road Race Engineering has a chart with the ACTUAL flow rates of all the fuel pumps that are compatible with DSMs. You can find that here:

http://www.roadraceengineering.com/fuelpumpflowrates.htm

You should see a total of Six Flow Rates per pump in the chart.
Each Pump was tested with 12V (Stock wiring) and 14V (Fuel Pump Rewire Mod).
Also, the pumps were tested with varying boost.

43psi = 0 lbs boost (base fuel pressure)
58psi = 15 lbs boost
73psi = 30 lbs boost

Soo.... long story long, on a stock-wired DSM with a boost controller set to 15lbs for example, the flow rate of the fuel would go from 73.82lph to 145.11lph by using the Walbro 190, as I understand it.

Hope that helps.
